Hydrogen is combusted in air at constant volume, with the reactants at an initial temperature of 298.15 K. The chemical reaction is

H₂ + 0.5 O₂ + 1.88 N₂ ? H2O + 1.88 N₂
This application will calculate the maximum pressure generated by the combustion process.

Thermodynamic properties are calculated using the empirical correlations provided by the ThermophysicalData package. The equations arising from the combustion enthalpy balance are solved numerically with fsolve.
